NAFTA has three primary dispute resolution mechanisms. Chapter 20 is the settlement mechanism for countries. It is often considered the least controversial of the three mechanisms, and has been maintained in its original form from NAFTA to the USMCA. In such cases, complaints filed by USMCA Member States against the duration of the contract would be violated.  In Chapter 19, the justifications for anti-dumping or countervailing duties are managed. Without Chapter 19, the avenue of recourse for the management of these policies would be through the national legal system. Chapter 19 provides that an USMCA body hears the case and acts as an international commercial tribunal to arbitrate the dispute.  The Trump administration has attempted to remove Chapter 19 of the new USMCA text, which until now existed in the agreement. Neither the worst fears of Canadian trade opponents – that open trade would erode the country`s manufacturing sector – nor the highest hopes of NAFTA proponents – that this would lead to a rapid increase in productivity – have been realized. Employment in Canada`s manufacturing sector has remained stable, but the productivity gap between the Canadian and U.S. economies has not been closed: until 2017, Canada`s labour productivity remained at 72% of the U.S. level.
National procedures for ratifying the agreement in the United States are governed by the legislation of the Trade Promotion Authority, which is also known as the fast-track authority. In 1994, the United States, Mexico and Canada, with the North American Free Trade Agreement (NAFTA), created the world`s largest free trade region, which generated economic growth and helped improve the living standards of the people of the three member countries. By strengthening trade and investment rules, this agreement has proven to be a solid foundation for building Canada`s prosperity and has provided a valuable example of the benefits of trade liberalization for the rest of the world. The new Canada-U.S.-Mexico agreement will strengthen Canada`s strong economic ties with the United States and Mexico. The CUSMA results, signed on the sidelines of the G20 of Heads of State and Government in Buenos Aires in November 2018, preserve key elements of long-term trade relations and contain new and updated provisions to address 21st century trade issues and foster opportunities for the nearly half a billion people who call North America at home. Democrats lamented that the agreement that Trump`s team had originally negotiated with Canada and Mexico shared a mistake with the treaty it needed to improve: it would be difficult to implement. In talking to Trump`s top representative, Robert Lighthizer, Democrats were able to find language that would have allowed countries or businesses to avoid sanctions by simply refusing to participate in dispute resolution bodies. NAFTA has boosted Mexican agricultural exports to the United States, which have tripled since the pact was implemented. Hundreds of thousands of jobs in the automotive industry have also been created in the country and most studies [PDF] have found that the agreement has increased productivity and reduced consumer prices in Mexico.
A trade agreement with Mexico and Canada revises Mexico`s labour laws and further encourages auto production in North America.
